DUMP-CAR.

Specification of Letters Patent.

Patented Oct. 19, 1909.

1'0 all whom it may concern:

Be it known that I, ARGYLE CAMPBELL, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Dump-Cars, of which thefollowing is a specification.

The object of my invention is to provide an improved construction ofdump car in which the door opening may be wider than the clear spacebetween the car wheels on opposite sides of the car.

My invention consists in the means I employ to practically accomplishthis object or result. That is to say, it consists in connection with adump car body having an opening wider than the clear space between thecar wheels from side to side, of two side doors hinged at theirlongitudinal outer edges adjacent to the longitudinal side edges of theopening and provided each with an inner door hinged at its outerlongitudinal edge to the inner longitudinal edge of the side door sothat the two inner doors may turn or swing in respect to the two sidedoors.

My invention further consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described, and more particularly specified in the claims.

In the accompanying drawing forming a part of this specification, Figure1 is a side elevation of a dump car embodying my invention. Fig. 2 is avertical cross section on line 22 of Fig. l and Fig. 3 is a plan view.

In the drawing, 1 represents a dump car having a body 2, with inclinedsides 8 and inclined ends 4, and a large central dump or dischargeopening 5 which extends in width nearly to the upright sides 7 of thecar, being thus much greater in width than the clear space between thecar wheels 8 0n opposite sides of the car. The door or discharge opening5 is preferably less than the clear space between the car wheelslongitudinally. Hinged at or near the longitudinal outer edge of thedischarge opening of the dump car on each side of said opening is alongitudinally hinged side door 9. Each of the longitudinally hingedside doors 9 is furnished with an inner longitudinally hinged door 10,which is hinged at 11 directly to the side door 9 at its inner lon- 10hinged thereto may be simultaneously opened and closed by any suitabledoor operating mechanism, the same preferably comprlslng an operatingshaft 13, a polygonal winding drum 14 thereon and connecting links 15adapted to wind around said polygonal drum, and connecting chains 16, 1718, 19 extending over pulleys 20, 21.

The main or side doors 9, 9 in connection with the inner of supplementaldoors 10, 10 each hinged to one of said main doors constitute a flexibleclosure for the discharge opening of the dump car.

I claim 1. In a dump car, the combination with a dump car body, having adischarge opening of greater width than the clear space transverselybetween the car wheels from side to side, of two longitudinally hingedside doors each having an inner door hinged directly thereto at itslongitudinal inner edge, substantially as specified.

2. In a dump car, the combination with a dump car body, having adischarge opening of greater width than the clear space transverselybetween the car wheels from side to side, of two longitudinally hingedside doors each having an inner door hinged directly thereto at itslongitudinal inner edge, and mechanism for opening and closing saiddoors, comprising an operating shaft, winding drum and connectionsextending from said drum to the inner edges of the side doors and to theinner edges of the inner doors carried by said side doors, substantiallyas specified.

3. In a dump car, the combination with a dump car body having adischarge opening greater in extent than the clear space between the carwheels, and a pair of doors hinged at their outer edges adjacent to theparallel sides of said discharge opening and each provided with asupplemental door hinged thereto at its inner edge, substantially asspecified.

4. In a dump car, a pair of inwardly extending doors together adapted topartially close the discharge opening, and each carrying an inwardlyextending supplemental door hinged thereto, said supplemental doorsclosing the remaining portion of said dis charge opening, substantiallyas specified.

5. In a dump car, the combination with an inwardly extending main dooradapted to partially close a discharge opening, and an inwardlyextending supplemental door carried thereby and hinged thereto at itsinner edge, substantially as specified.

6. In a dump ear, the combination with a main door adapted to partiallyclose a discharge opening, and a supplemental door carried thereby andhinged thereto at its inner edge, and an operating shaft, winding drumand connections from said drum extending to the inner edge of the maindoor and to the inner edge of the supplemental door carried by said maindoor, substantially as specified.

7 In a dump car, the combination with a car body having a dischargeopening, of two inwardly extending main doors hinged to the car body andpartially closing said opening,

each of said main doors being provided with an inwardly extendingsupplemental member flexibly connected thereto for closing the remainingportion of said discharge open ing, substantially as specified.

8. In a dump car, the combination with a car body having a dischargeopening, of an inwardly extending main door hinged to the body andpartially closing said opening, and provided with an lnwardly extendingsupplemental member flexibly connected thereto ARGYLE CAMPBELL.
